~~~ Hawaii Weather Narrative ~~~
The trade winds will gradually increase this weekend…continuing into the first part of the new work week ahead. Here’s a weather chart showing a couple of near 1020 millibar high pressure systems located to the northeast of the islands. There’s also a weak low pressure system to the south of the state. The models are now showing a reduction in our trade wind speeds by around the middle of the new week. This will occur as an area of low pressure edges towards our area aloft.
A few showers will visit the windward sides…although the next several days will be generally dry most other areas. Satellite imagery shows scattered low clouds over the ocean upstream of the islands, while the leeward sides were mostly clear to partly cloudy. There’s a new area of high clouds out over the ocean to our west. Here’s the looping radar image, showing a few showers falling over the nearby ocean…and over the central islands in places. ~~~ I’ll be back with your next new weather narrative Saturday morning. I hope you have a great Friday night wherever you’re spending it! Aloha for now…Glenn.
Glenn on Maui: I was in the Haleakala Crater twice last week, walking down Sliding Sands Trail, with two different friends, it’s such a great place to visit…and just up the hill from me! I’m just heading out on my first two mile fast walk of the day, with a second scheduled for early this afternoon…I enjoy these very much! It’s Friday, so of course I’ll be checking out the latest films showing in Kahului, and will let you know which one I decide on later in the day. So, it’s summer, full-on summer, and the weather here in the islands sure feels that way. I must admit that I’m already starting to look forward to the upcoming autumn season, for various reasons…which I’ll discuss in more detail at some point. It was another typical partly to mostly cloudy afternoon here in upcountry Maui…at least here in Kula. Glancing over towards the windward and leeward beaches, they look mostly clear in contrast. Interesting, looking at the latest news, it appears that the United States Navy is readying for an attack on Syria!
Friday night film: There are so many good looking films playing now, although several of them are just opening…which can often leave them too crowded. So, I’ll see one, that some of you may roll your eyes over, called The Wolverine. It stars Hugh Jackman, Will Yun Lee, Hiroyuki Sanada, Hal Yamanouchi, Rita Fukushima, and Famke Janssen…among many others. The synopsis: Logan, the eternal warrior and outsider, finds himself in Japan. Out of his depth in an unknown world, he will face a host of unexpected and deadly opponents in a life-or-death battle that will leave him forever changed. Vulnerable for the first time and pushed to his physical and emotional limits, he confronts not only lethal samurai steel but also his inner struggle against his own immortality. ~~~ Looking at what the reviews and critics say, they’re being quite generous with this action/adventure film. It’s a long 2 hours and 6 minutes, although I like long films usually. I know for sure that it’s going to be full of violence, and intense sci-fi action, which I don’t mind typically. If you’re interested in taking a look…here’s a trailer for you.
World-wide tropical cyclone activity:
Atlantic Ocean: There are no active tropical cyclones

OTHER SYSTEMS WITH FORMATION POTENTIAL BEYOND 48 HOURS…
A TROPICAL WAVE IS MOVING ACROSS CENTRAL AMERICA AND ENTERING THE EASTERN PACIFIC OCEAN. ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR DEVELOPMENT OF AN AREA OF LOW PRESSURE SOUTH OF THE SOUTHERN COAST OF MEXICO BY THE MIDDLE OF NEXT WEEK. THIS SYSTEM HAS A LOW CHANCE...NEAR 0 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS...AND A HIGH CHANCE...60 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 5 DAYS.
Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.
Central Pacific Ocean: There are no active tropical cyclones
An area of thunderstorms about 800 miles south of Honolulu Hawaii moved west at around 15 mph. Convection associated with this feature pulsed irregularly, but satellite estimates of wind data suggested the presence of a low-pressure center. Excessive shear in the environment will only permit this feature to intensify slowly at most. The feature has a low chance, 10 percent, of becoming a tropical cyclone during the next 48 hours.

Interesting: Refrigerated Trucks To Use Fuel Cell Technology – In order to transport our favorite ice creams, frozen foods, and fresh produce, certain trucks are equipped with powerful refrigeration systems often powered by small diesel engines. These engines are constantly running all the way from the manufacturers of these frozen goods to the market in order to keep these groceries frozen or cool. As a result, refrigeration trucks tend to use more energy and resources to run.
In an effort to reduce some reduce emissions and use a quieter, more efficient alternative to these refrigeration units, researchers at the U.S. Department of Energy’s Pacific Northwest National Laboratory are overseeing a project that will use an alternative energy source: fuel cells.
A project using trucks whose refrigeration units are powered by this clean technology will be conducted in Texas, California and New York.
The fuel cells will do the work normally done by a small diesel engine, which keeps the cargo at the proper temperature while the trucks are making deliveries. Each of the four trucks will still be equipped with a main diesel engine that actually powers the truck.
Researchers conducting the experiment believe this will be the first time that refrigerated trucks making deliveries have been equipped with a fuel cell — a device that creates electricity by driving chemical reactions using hydrogen and air. The only byproducts are heat and water.
“This is a great application for a fuel cell,” said Kriston Brooks, the PNNL researcher leading the project. “A trailer refrigeration unit traditionally is powered by a small diesel engine or electric motor that drives compressors to provide cooling to the cargo. A fuel cell can potentially provide a clean, quiet and efficient alternative by powering the electric motor.”
Industry officials estimate that approximately 300,000 refrigerated trucks with auxiliary power units are on the road in the United States. By replacing the small diesel engines with the more efficient fuel cell, users will see fuel savings of approximately 10 gallons a day per unit, in addition to reduced emission of pollutants and significantly quieter operation.
“Accelerated fuel cell use in this application is also expected to create jobs in the energy sector, increase fuel cell manufacturing volume, decrease costs, and catalyze a stronger domestic supplier base,” said Jamie Holladay, PNNL’s sector manager for fuel cell technologies.
Fuel cells are becoming more common as energy sources in buildings and in vehicles such as buses. While the devices are generally more expensive than traditional forms of energy generation, many scientists and product developers expect that as they become more widely adopted and production levels increase, their cost will come down, similar to what has happened to products like cell phones.
